PART A: The equation I used is y<span>≥-1x+4. The line will be graphed going diagonally from the second quadrant to the fourth quadrant and shaded above the line.

PART B: Plug in the coordinates for point C and F into the equation from PART A and solve them to make sure the statements are true. You should end up with 2</span>≥2 for point C and 4<span>≥1 for point F.

PART C: First graph the equation and then shade below the line. Next, identify all the points in the shaded area. 

I hope this helps you! I have provided pictures of both equations for reference. The first picture is for PART A and PART B. The second picture is for PART C. Let me know if I'm correct :)</span>

If a=(1 2 3 4) find A×A and the relation determined by (I) y=2x (II) x+y​
kiruha [24]

Answer:

HOPE IT HELPS PLZ MARK ME BRAINLIEST

Step-by-step explanation:

A={1,2,3,4,5,6}

R={(x,y):y is divisible by x}

We know that any number (x) is divisible by itself.

(x,x)∈R

∴R is reflexive.

Now,(2,4)∈R [as 4 is divisible by 2]

But,(4,2)∈ /

R. [as 2 is not divisible by 4]

∴R is not symmetric.

Let (x,y),(y,z)∈R. Then, y is divisible by x and z is divisible by y.

∴z is divisible by x.

⇒(x,z)∈R

∴R is transitive.

Hence, R is reflexive and transitive but not symmetric.

Person A buys 12 granola bars and 7 cups of yogurt for $15.50. Person B buys 6 granola bars and 11 cups of yogurt for $11.50. Fi
Hitman42 [59]

Let us assume that cost of each granola bar be $x and that of a cup of yogurt be $y  
From person A's purchase, we get  
12x + 7y = 15.5; equation A  
And from person B's purchase, 
6x + 11y = 11.5; equation B  
Let us multiply equation B by 2 and subtracting equation A from it, we will get  
12x + 22y - 12x - 7y = 23 - 15.5,  
=> 15y = 7.5 
or, y = 0.5  
Substituting value of y in equation A, we can find x  
12x + 7*0.5 = 15.5 
=> x = (15.5 - 3.5)/12 
or, x = 1  
Therefore, cost of granola bar is $1, and that of yogurt is $0.5

The formula for the volume of a right circular cone is shown. Rewrite the formula so that it expresses the height h in terms of
zlopas [31]

Height of cone in term of volume is 3V / πr²

<u>Given that;</u>

Volume of cone = (1/3)(πr²h)

<u>Find:</u>

Height of cone

<u>Computation:</u>

We know that;

Volume of cone = (1/3)(πr²h)

We have to calculate height from above given formula.

V = (1/3)(πr²h)

3V = πr²h

3V / πr² = h

So,

Height of cone = 3V / πr²

<em>Height of cone</em> in term of volume = 3V / πr²
